Which of the following disorders involves inflammation of joints?
The NCERT definition for arthritis is 'Arthritis: Inflammation of joints.'
A disorder causing fatigue, weakening, and paralysis of skeletal muscle due to an autoimmune attack on the neuromuscular junction is:
The NCERT text defines Myasthenia gravis as an 'Auto immune disorder affecting neuromuscular junction leading to fatigue, weakening and paralysis of skeletal muscle.'
Which of the following is an age-related disorder impacting bone structure and increasing fracture risk?
The NCERT text states: 'Osteoporosis: Age-related disorder characterised by decreased bone mass and increased chances of fractures.'
Match List I (Type of Joint) with List II (Found between):
| List I | List II |
|---|---|
| A. Cartilaginous Joint | I. Between flat skull bones |
| B. Ball and Socket Joint | II. Between adjacent vertebrae in vertebral column |
| C. Fibrous Joint | III. Between carpal and metacarpal of thumb |
| D. Saddle Joint | IV. Between Humerus and Pectoral girdle |
Cartilaginous → between vertebrae; Ball & socket → shoulder; Fibrous → skull; Saddle → carpal/metacarpal of thumb.
Which of the following statements are correct regarding skeletal muscle?
A. Muscle bundles are held together by collagenous connective tissue layer called fascicle. B. Sarcoplasmic reticulum of muscle fibre is a store house of calcium ions. C. Striated appearance of skeletal muscle fibre is due to distribution pattern of actin and myosin proteins. D. M line is considered as functional unit of contraction called sarcomere.
D wrong — sarcomere is between two Z-lines, not the M-line.
Three types of muscles are given as (a), (b) and (c) (a — striated/skeletal; b — smooth/non-striated; c — branched/cardiac). Identify the correct matching pair along with their location in human body:
Striated muscle is skeletal (e.g. triceps); smooth muscle lines viscera like the stomach; cardiac muscle is in the heart.
Match List I with List II:
| List I | List II |
|---|---|
| A. Fibrous joints | I. Adjacent vertebrae, limited movement |
| B. Cartilaginous joints | II. Humerus and Pectoral girdle, rotational movement |
| C. Hinge joints | III. Skull, don't allow any movement |
| D. Ball and socket joints | IV. Knee, help in locomotion |
Choose the correct answer from the options given below:
Fibrous — skull (immovable); cartilaginous — vertebrae; hinge — knee; ball-and-socket — humerus/pectoral girdle.
